A major security breach with a health care company could affect more than 38,000 members, Action 7 News reported.

A woman, who did not want to be identified, told Action 7 that her trust was compromised when she received a letter from Aetna Health Care.

She said the letter explained that a laptop with sensitive information was stolen on April 14 from an Aetna Health Care employee's personal car.

The computer allegedly contains information such as addresses, birthdates and Social Security numbers.

The letter said that mainly civilian employees of the Department of Defense might need to take some extra steps to keep their information safe, the woman said.

"(I) feel very uncomfortable and it makes me uncomfortable to think that my information was still in their computer," the woman said.

Aetna apologized to its customers through a letter from its CEO, which was sent to Action 7.

"Our employee did not follow our corporate policies, and it was coupled with a criminal theft," the statement said. "In light of this, we are augmenting out efforts to ensure employee compliance with all Aetna security requirements."

The company is also offering to pay for credit monitoring services, something the unidentified woman planned to take advantage of.
